>I was playing with ipfw pipes. I added pipes limiting bandwidth to
128Kbps and 64Kbps to/from the server etc.. then after a few days when I
took the >firewall rules off of the server but the bandwidth stayed the
same.. I only get 128Kbps to the server from my personal pc and all other pc's.
>The server is on the same 10/100Mb switch as me and the other pc's.

again... but then downloading freezes after 4096 bytes of data...
